Legal noise limits in Spain and who sets them

Key rules

• Who sets limits: Your town hall's ordinance sets the limits that apply to you, so check your own city.
• Illegal noise: Noise is illegal if it is over the measured limit, breaks hours or behaviour rules, or is persistent.
• No measurement needed: The Policía Local can act on shouting and parties without measuring.
• Bedrooms: Bedrooms have the strictest indoor limits, and night limits are lower than day limits.

The short answer

Noise is illegal when it breaks your town's rules. That means it is over the measured limit, it happens at forbidden hours, or it is persistent and a real nuisance. Ordinary living noise that stays under the limits, or happens only now and then, is annoying but not illegal.

Who sets the limits

Spain has a national noise law. It sets general quality targets and the types of zone, such as residential, industrial and leisure areas. A separate building code sets how well buildings must block sound.

The detailed limits that matter to you come from your ordenanza (the town hall's noise ordinance). It sets limits by zone and by time of day, and it also sets inspections and fines. Some regions, such as Catalonia, Valencia and Andalusia, also have their own noise laws. So the numbers differ from city to city.

What counts as illegal

Noise is a problem you can act on in any of these cases:

• Over the limit. A technician measures it with a calibrated sound meter and it exceeds the ordinance limit.
• Breaking a behaviour or hours rule. Examples are shouting, parties at night or a banned activity. The Policía Local can act on this without any measurement.
• Persistent and a nuisance. This can also be pursued in civil court as an "actividad molesta" (a nuisance activity), where you can ask for the noise to stop or for damages.

Only extreme, sustained noise that harms health reaches the criminal level.

Indoor limits

For noise coming into your home, ordinances usually set indoor limits by room. Bedrooms are strictest, and night limits are lower than day limits. In big cities the airborne-noise values are generally around 30-40 dB(A) depending on the room. Limits also differ for airborne noise, impact noise (footsteps, dragging furniture) and equipment such as air conditioning. Read the exact values in your own ordinance.

Find your city's rules

Start on your town hall's website and look for the ordinance, usually under the environment section. The checklist below gives the search terms and the next steps. The Policía Local or the town hall's environment department can confirm the current text and your address's noise zone.

If the noise is happening now, call the Policía Local. For a formal complaint, follow the process below.

Choosing between options

Is the noise you hear illegal or just annoying?

• Illegal: over the limit: A technician with a calibrated sound meter measures noise above your ordinance's limit for your zone, room and time of day.

• Illegal: breaks the rules: The noise breaks rules on hours, behaviour or banned activities, or is persistent enough to be a real nuisance. Shouting and parties can be reported to the local police without measurement.

• Merely annoying: The noise is occasional or normal living noise and stays under the limits. You can talk to your neighbour, but the town hall is unlikely to sanction it.

If the noise is over the measured limit, breaks hours or behaviour rules, or is persistent, treat it as actionable and go to the town hall; otherwise treat it as annoying.

Confirm the exact limits for your city and room in the current ordinance before acting.

Making a formal noise complaint to your town hall (ayuntamiento)

• Gather your evidence and details of the noise: before you file

• Find your town hall's noise or environment department (medio ambiente), which handles inspections together with the local police: before you file

• File a written complaint (instancia or denuncia) online through the town hall's electronic office with a digital certificate or Cl@ve, or in person at a citizen service office or registry. Include your name and contact details, the address of the noise, what the noise is, the hours and how often it happens, the name of the person or business if you know it, and your evidence: once your evidence is ready

• Call the local police for noise that is happening right now, since urgent cases are handled by phone rather than by written complaint: while the noise is happening

• Expect an inspection or local police measurement: in practice within days or weeks, depending on the city and its workload

• Wait for the written answer to your complaint: the town hall must answer within the period set by its own rules, and if none is set, within three months at most

• Follow a sanction procedure if one is opened against the neighbour or business: often takes months; these procedures commonly lapse after six months to a year

• Chase the town hall in writing, quoting your complaint's registration number, if you hear nothing: once the response period has passed

Checklist

• Search your town hall (ayuntamiento) website for "ordenanza de ruidos", "ordenanza de protección contra la contaminación acústica" or "ordenanza de convivencia", usually under Normativa or Medio Ambiente.

• Search the web for "ordenanza ruido" plus your city name and "BOP" to find the text published in the provincial or regional official bulletin.

• Read the limits for your zone and for night-time, and check which night hours your city uses.

• Find the indoor limit for the room affected, since bedrooms are stricter than living rooms and night limits are lower than day limits.

• Email or ask at the town hall registry for the ordinance if you cannot find it online.

Frequently asked questions

Can I report noise without a measurement?

Yes, the local police can report behaviour noise such as shouting or parties without any measurement, but limits on machines, music systems or installations need a technician's reading. A technician uses a calibrated sound meter (sonómetro) and compares the result with your town's limits. Fines for this come from the town hall.

When does noise become a criminal matter?

Noise becomes a criminal matter only when it is extreme, sustained and harms health. Most neighbour noise never gets there and is handled by the town hall or, in a civil case, by a court that can order the noise to stop or award damages.

Do regions have their own noise laws too?

Yes, some regions such as Catalonia, Valencia and Andalusia have their own noise laws on top of the national framework. Your town hall's ordinance is still the text that sets the zone and time limits you will be measured against.

Are indoor noise limits the same in every city?

No, each city sets its own indoor limits, though they are broadly similar. They are generally around 30-40 dB(A) inside homes depending on the room, with bedrooms strictest and limits lower at night.
